Solenoid heat??

Hi all,

Is it normal for a co2 reg solenoid to get hot? Or just quite warm to the touch? Noticed mine today was kicking out some heat. It’s a strideways dual stage system so im presuming the solenoid is good quality.

Thanks
 
The 240 volt can get a bit hot and the 12 volt ones seem to run much cooler IME
Hi there,
Thanks for your reply, it’s the 12v one apparently 🤷‍♂️ still quite warm to my touch but I guess it’s just “on” and that causes the heat.

If we get hold of the plastic sides of our Mains solenoid you can hold it all the time, just warm, but ours has a metal end to it and thats much hotter but not burning.
One thing to note, the heat from the solendoid may affect the bubble counter, on ours, if you adjust it when just switched on, Cold, you may find after a hour or so the bubble rate changes as heat ( slight) builds up in the whole unit, so best to readjust again.
 
Lucky you have the 12V ones as the 240V ones get pretty hot in comparison

Its the needle valves that are more susceptible the flow rates changes with temps - esp the cheapo needle valves most of us use
 
Under ordinary operation, solenoids get warm (if not hot) to the touch. The temperature of a solenoid can easily be between 65C and 100C (less once you account for the plastic insulation).
